Hell trinkets aren't exactly an upgrade for Violet....
The loss of the +1 to special skills from the harpas 2/2 set is totally not worth the increase in tcp from the 3/3 hell trinkets.
I could get the master cube for Ex Camellia Drop before by getting a +1 from modules but now will need +1 on 2 modules instead and I also lose the master cube from FM4 which is my 2nd exceed source. Otherwise I have to use the 4/4 extreme to replace the above which means I cant use the epsilon 6/9 for the sweet +5 exceed artistry/strike and +3 basic atk.
I could go get the tunes needed but this ojousama is seriously spending more money than she is earning
